Shinsou was your best friend in middle school. Both of you shared a love for heroes, so you quickly bonded. But he liked you a little... too much. He hated when other people were around you or asked for your number, to the point where it had become a problem. He wanted you to himself.

You were calmly talking to a guy you had run into at a grocery store while shopping with Shinsou, and he was glaring intently at the man as if threatening him.
